Last weekend I saw the documentary Joseph Pulitzer: Voice of the People. Pulitzer, as you probably know from the prize named after him, was a major newspaper publisher...Lance FortnowFrom Computational Complexity | February 21, 2019 at 07:42 AM

So you've got an iPhone XS in Space Grey. Congrats, so do 20 million other people. Maybe you have different cases but otherwise the hardware in all these phones...Lance FortnowFrom Computational Complexity | February 14, 2019 at 07:52 AM

As a grad student in the late 80's I had the opportunity to witness many great and often surprising theorems in computational complexity. Let me tell you aboutnondeterministic...Lance FortnowFrom Computational Complexity | February 7, 2019 at 07:47 AM

The Chronicle of Higher Education recently published a story Phishing Scheme Targets Professors’ Desire to Please Their Deans — All for $500 in Gift Cards. TheFrom...Lance FortnowFrom Computational Complexity | January 31, 2019 at 11:46 AM

My daughter Molly spent six weeks on an environmental program in China last summer. When she got back she had to do a report on machine learning and wind turbines...Lance FortnowFrom Computational Complexity | January 24, 2019 at 08:58 AM

Shockingly I've never done a post on search versus decision, one of the more interesting dualities in complexity. In short: Decision: Is there a needle in the haystack...Lance FortnowFrom Computational Complexity | January 9, 2019 at 08:10 AM

Result of the year goes to
Oracle Separation of BQP and PH by Ran Raz and Avishay Tal
which we wrote about in June. This work solves one of the original openQuanta...Lance FortnowFrom Computational Complexity | December 31, 2018 at 07:25 AM

A few weeks ago as Bill and I prepared for our upcoming year in review post, we noted that we hadn't lost any theoretical computer scientists this year, at least...Lance FortnowFrom Computational Complexity | December 26, 2018 at 08:31 AM

Here's an open question that goes back to a 2003 paper that I wrote with Steve Fenner, John Rogers and Ashish Naik. The conference paper goes back to 1996.
In...Lance FortnowFrom Computational Complexity | December 13, 2018 at 09:53 AM

Today is the national day of mourning for George Herbert Walker Bush, one of the best presidents for science and computing. He created PCAST, the President's...Lance FortnowFrom Computational Complexity | December 5, 2018 at 09:03 AM

H. Venkateswaran, a much loved professor in the School of Computer Science at Georgia Tech and a fellow computational complexity theorist, is retiring at the end...Lance FortnowFrom Computational Complexity | November 28, 2018 at 01:27 PM

I'm spending this week at the Simons Institute in smokey Berkeley, California. This fall Simons has a program in Lower Bounds in Computational Complexity. Scroll...Lance FortnowFrom Computational Complexity | November 15, 2018 at 11:59 AM

With all the news about elections, caravans, shootings and attorney generals, maybe you missed the various stories about real transformations at our top universities...Lance FortnowFrom Computational Complexity | November 8, 2018 at 09:00 AM

In Bill's post earlier this week, he asks if there is a fixed algorithm such that if P = NP, this algorithm will correctly compute satisfiability on all inputs....Lance FortnowFrom Computational Complexity | November 1, 2018 at 06:33 AM

Sometimes you see a beautiful theorem A that you love to talk about. Then another beautiful theorem B comes around, making the first one meaningless since B trivially...Lance FortnowFrom Computational Complexity | October 25, 2018 at 07:24 AM

Imagine the following not-so-unrealistic scenario: The US-China trade war deepens leading to a cold war. The US blocks all Chinese citizens from graduate school...Lance FortnowFrom Computational Complexity | October 18, 2018 at 09:23 AM

As we do every year at this time, we help you find that perfect academic job. So who's hiring in CS this year? Perhaps we should instead follow the advice of John...Lance FortnowFrom Computational Complexity | October 11, 2018 at 09:27 AM

Lance: It's Friday afternoon and the Dagstuhl workshop has ended. We have some time before we need take off so how about one final typecast.
Bill: Always a good...Lance FortnowFrom Computational Complexity | October 1, 2018 at 05:06 PM

Lance: Bill, in our typecast earlier this week I said you were older than me. But 68? You don't look day over 66.
Bill: Neither do you. But seriously, why do you...Lance FortnowFrom Computational Complexity | September 27, 2018 at 02:44 AM
